for what it's worth, as a captain myself, I would accept any lineup change if it lead to more/all matches being completed. Ideally, no "tier" improvement would occur in such a situation.
I am just "sharing" my thoughts; not calling or demanding for any type of rule "change" or specific interpretation.
good luck all & thanks to Slor, Boots and all other players & volunteers for a fun tournament.
the most successful/active teams should think about meeting up for a "fall cup"
cheers
